  "id": "MLC-T-CHM-005558",
  "term": "Hypsochromic shift",
  "field": "Chemistry",
  "definition": "A shift of an absorption or emission band to shorter wavelengths (higher energy) in a spectrum. This phenomenon is also known as a blue shift. It can be caused by changes in solvent polarity, pH, or molecular conformation that alter the electronic energy levels of the chromophore.",
